PETER JOHAN ADOLF PETERSON, 01- PINE RIVER, MINNESOTA, ASSIGNOR OF ONE- HALF TO OLAF B. ORRES, OF PINE RIVER, MINNESOTA.

NUT-LOCK AND RAIL-JOINT PROTECTOR.

Application filed May 26,

To all whom it may (once/n lie it known that I, Pn'rnn JoHAN ADOLF In'rnnsoN a citizen of the United States, residing at line River, in the county of Cass and tilate of Minnesota, have invented certain new and useful Improvements in Nut- Loclrs and IIail Joint Protectors, oi which the Following is a specification.

This invention relates to improvements in wanliine l nut im'h'S and rail joint protectors and its object is to provide a device that serves eiiectuallv to unite the meeting ends of railway rails in such manner as to produce the effect of one continuous rail and so eliminate the jolt and 1 ibration ordinarily caused by the passage of the train wheels over worn rail ends; and to prevent the rail-connecting elements from loosening or becoming defeetive from wear. A further object is to provide a device of this class that is of few parts and cheap to manufacture.

W'ith the toregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereina'i'ter fully described, pointed out in the appended claim and illustrated in the accompanying drawing which forms a part of this specification and in which- Figure 1 is an end view of Fig. 2.

Fig. 2 is a fragmentary view of two railway rails showing the application of my device.

Fig. 3 is a plan view of the cover plate em ployed.

Like reference characters denote corresponding parts throughout the several views.

The reference numerals 1, 2 denote the meeting ends of two railway rails which are provided with the usual fish plates 3, 4 which are secured in position by the usual bolts 5 and nuts 6 and by the small bolts or pins 7 provided with the cotter pins 8. To one of the fish plates 3 I apply a cover plate 9 formed with the large square perforations Specification of Letters Patent.

1919. Serial No. 299,811.

1.0 and with the small circular perforations 11. The bolts and nuts 5, 6 are first placed in operative position to secure the fish plates firmly in position and the cover plate 9 is then applied directly to one fish plate, the a-rforatiisins-l 0 being of such size as to snugly receive the nuts 6 which are prevented from turning or working oil the bolts by said plate. The cover plate is secured firmly in engagement with the fish plate 3 by means of the pins 7 and (-otter pins 8.

The cover plate is oi such depth that when it rests upon the inclined base portion of the fish plate it extends to approximately the level of the tread surface of the rails, the top edge of the cover plate being gently curved so that the train wheels will noiselessly engage it without jolt or vibration when passing over the rail ends. It is obvious that the cover plates will positively retain the bolts and nuts 5, 6 in operative position thereby positively retaining the rail ends in operative relation.

IVhat is claimed is In combination with the meeting ends of a pair of railway rails, fish plates. bolts connecting said fish plates to the rails, nuts for said bolts, one cover plate for each pair of fish plates, said cover plate being formed with a plurality of square perforations adapted to snugly receive the said nuts when the cover plate is applied to one of said fish plates and to said bolts, said cover plate, when in position, extending from the base of one fish plate to the level of the tread surface of the railway rails at the rail ends, and fastening means for said cover plate.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two subscribing witnesses.

PETER JOHAN ADOLF PETERSON.
